Anything less than two weeks away from the writing cave is a grand excuse to Febreeze the creative closet. That TBR pile isn't going to shrink itself.
Any trip longer than two weeks and I try to write during the afternoons/heat of the day since I'm a bit vampiric. I tend to focus on the many aspects of being an author that don't involve crafting the actual story. Those aspects tend to be more forgiving of interruptions. Also, I don't try to write during any actual movement parts of travel. Why?
I am the seat snorer.
This Pavlovian puppy was trained to sleep during all modes of transportation. Plane? Sleep. Car? Sleep. Train? Sound asleep. Ship? No sleep. Find your sea legs first, then the buffet. ~oink~
Travel, definitely not a time when I get work done.
